Application testing fundamentals of software testing

2. Application test is an activity that every software tester performs daily in his career. These two words are extremely broad in practice. However, only the core areas and the most important areas are discussed. The purpose of this article is to touch all primary areas so that readers can receive all the basic briefing in a single place.

3. Application Test Methods Black Box: in the black box Test, the AUT is validated against its requirements, taking into account the inputs and expected outputs, regardless of how the inputs are converted into outputs. Testers are least concerned with the internal structure or code that implements the application's business logic. There are four primary techniques to design test cases for black box testing:

4. White Box: main focus of this methodology is to validate how the application's business logic is implemented through code. Internal structure of the application is tested, and the techniques available to do this are : • Code coverage * Path coverage

5. Grey Box: practically speaking, this is a mix of black box and white box. In this methodology, the tester mainly tests the application as in black box. But for some business-critical or vulnerable application modules; Tests are performed as a white box.

6. Here is a list of the most important and basic features provided by almost all function test tools. * Record and Play * You can parameterize the values • Script editor * Run (the test or script, with debug and update modes) • Report of the session

7. Below is the list of the few widely used function test tools. * HP QTP (quick test Professional) • Selenium * IBM Rational Robot * Test Completed * Push test * Telerik

8. Smoke test: the first testing cycle that is wide and shallow in approach. The purpose of the smoke test is to verify that there are no crashes in the application and that it is suitable for further Tests. Sanity Testing: the second test cycle, which is narrow and deep in its approach. Its purpose is to verify that a particular module is functioning properly and is suitable for full testing. Functional tests: the proper and complete examination of the application is carried out in this cycle. The focus of this work lies in the verification of the business logic of the application. Regression tests: this is the last test cycle in which the Bugfixes and/or updates are checked. In addition, regression testing also ensures that there are no malfunctions in other areas of AUT due to fixes and changes. For more details: https://www.exltech.in
